Nope, those are all handled server-side.
If you're constantly failing them, then you're probably doing the silver and gold missions, or the APEX missions. These missions are higher tier and APEX missions are incredibly difficult for the strike teams, hence why they are tied to MP.
Make sure when you're starting, that the missions you do are bronze tier.
